I am using Python 2.7 on Windows 8.1 46 bit.
I want to install divisi2
I have installed NumPy and SciPy which are the pre-requisites for divisi2 already. I have installed Visual C++ for python 9.0.
Whenever I issue the pip install divisi2
command I get the following error in the console.
svdlib/svdwrapper.c(89) : error C2059: syntax error : '{' svdlib/svdwrapper.c(90) : error C2275: 'PyObject' : illegal use of this type as an expression c:python27includeobject.h(108) : see declaration of 'PyObject' svdlib/svdwrapper.c(90) : error C2065: 'arr' : undeclared identifier svdlib/svdwrapper.c(90) : error C2065: 'type' : undeclared identifier svdlib/svdwrapper.c(90) : warning C4047: 'function' : 'PyArray_Descr *' differs in levels of indirection from 'int' svdlib/svdwrapper.c(90) : warning C4024: 'function through pointer' : different types for formal and actual parameter 2 svdlib/svdwrapper.c(91) : error C2065: 'dim' : undeclared identifier svdlib/svdwrapper.c(91) : warning C4047: 'function' : 'npy_intp *' differs in levels of indirection from 'int' svdlib/svdwrapper.c(91) : warning C4024: 'function through pointer' : different types for formal and actual parameter 4 svdlib/svdwrapper.c(91) : error C2065: 'strides' : undeclared identifier svdlib/svdwrapper.c(91): warning C4047: 'function' : 'npy_intp *' differs in levels of indirection from 'int' svdlib/svdwrapper.c(91): warning C4024: 'function through pointer': different types for formal and actual parameter 5 svdlib/svdwrapper.c(95) : error C2065: 'arr' : undeclared identifier svdlib/svdwrapper.c(96): error C2065: 'arr': undeclared identifier svdlib/svdwrapper.c(96): warning C4047: 'return': 'int *' differs in levels of indirection from 'int' svdlib/svdwrapper.c(100) : error C2143: syntax error : missing '{' before '*' svdlib/svdwrapper.c(102) : warning C4133: 'initializing' : incompatible types - from 'int *' to 'PyObject *' svdlib/svdwrapper.c(114) : warning C4133: 'return' : incompatible types - from 'PyObject *' to 'int *' error: command 'C:\Users\i054564\AppData\Local\Programs\Common\Microsoft\Visual C++ for Python\9.0\VC\Bin\cl.exe' failed with exit status 2 ---------------------------------------- Command "c:python27python.exe -u -c "import setuptools, tokenize;__file__='c: users\i054564\appdata\local\temp\pip-build-0aufqt\divisi2\setup.py';exec (compile(getattr(tokenize, 'open', open)(__file__).read().replace('rn', 'n'), __file__, 'exec'))" install --record c:usersi054564appdatalocaltemppip-5dxl7g-recordinstall-record.txt --single-version-externally-managed --compile" failed with error code 1 in c:usersi054564appdatalocaltemppip-build-0aufqtdivisi2

I finally solved this problem after getting this hint from a colleague i.e. to use
https://github.com/develersrl/gccwinbinaries.
This will install the requisites and then you can install divisi2.
